thermostat opening late ???
hi, my car has been running hot , i noticed that the thermostat (fender test) doesnt open until 9:30. i know its supposed to at 8. now is my thermostat going bad, or somethin else. iam assuming there is some kind of sensor that would feed the termostat info to open?
thanks in advance

right!!!
actually it has been this way since i bought it, but i didnt bother since it goes down as soon as the oil cooler fan kicks in.
anyone ?

That was how mine behaved before it failed. It began to open at higher temperatures until finally it just closed and never opened. I didn't realise it was happening since I was new to the car and it was spring, I thought maybe that was just the way it worked in the warmer temps.
IIRC, there's no sensor - I think maybe a bimetallic strip-like arrangement in the thermostat itself? I could be wrong...

is that right?? well sometimes the car would run really cold, which tells me that the thermostat opened in time, but most of the time the temp is at 9.
i guess i may have to replace it in the near future.
thanks

yes 90% of the time the car run at between 9 and 9:30.
i guess to clean it , i will have to take it out??? if so, i rather put a new one, cause it looks like a lot of work

You can get a new inner part I have read and just replace that.

I recall being told a long time ago that the way to test a thermostat is to take it out, place it in a pan of water and put it on the stove w/ a thermometer. When the temp goes up as the water gets hot you can see it open and thus determine the opening temp.
This suggests that there is no sensor to open the thermostat. It opens on its own via some temp.
Seems to me like its going bad.

Yeah, I thought of mentioning that, but my point was more to the question of "how does it open". But thanks for the clarification.
OT: By the way, how do I set a signature?

I'm not sure you have an oil temp problem .
The temp gauge isn't calibrated , so we do not know what the real temp is .
It could read high or low in comparison to another car .
Until you test the gauge by reading the oil temp on another thermometer ...
If the thermostat opens and closes it is still working somewhat .
dfinnegans test will work well if you use oil in place of the water .
A meter gives the most accurate misinformation available .
Never blindly put your trust in any uncalibrated meter .
